为明确不同寄主和不同信息化合物对豆大蓟马的行为影响,本文应用“Y”型嗅觉仪测定了豆大蓟马雌成虫对两种寄主植物花和不同浓度(v/v)下11种化合物的趋向性反应,结果表明:豆大蓟马对豇豆花、10-4烟酸乙酯、10-6烟酸乙酯、10-2橙花醇、10-2芳樟醇、10-6邻茴香醛和10-23-苯丙醛、10-43-苯丙醛具有极显著的趋向反应;对四季豆花和10-4橙花醇具有显著的趋向反应;10-4β-香茅醇、10-6β-香茅醇和10-6苯甲醛对豆大蓟马具有显著的驱避反应。不同浓度同一化合物对豆大蓟马的吸引作用也存在显著差异。实验结果可为进一步开发利用信息化合物田间防治豆大蓟马提供参考。
In order to clarify the effect of different hosts and different information compounds on the behavior of T. chinensis, we used the “Y” Eleven compounds of the trend of the reaction, the results showed that: Thrips leguminous cowpea, 10-4 ethyl nicotinate, 10-6 ethyl nicotinate, 10-2 nerol, 10-2 linalool, 10 -6-o-anisaldehyde and 10-23-phenylpropionaldehyde, 10-43-phenylpropionaldehyde have a very significant trend response; Soybean and 10-4 neroli significant trend reaction; 10-4β-lemongrass Alcohol, 10-6β-citronellol and 10-6 benzaldehyde have a significant repellent response to the soybean thrips. Different concentrations of the same compounds on the thrips Snapshot Thrips also significant differences in the role of attraction. The experimental results can provide reference for further development and utilization of information compounds in the field of soybean thrips.
